[CARBONDATA-2016] Exception displays while executing compaction with alter
query
**Root Cause**
When we apply the alter table command to add column with default value it
is storing it as long object,it is wrongly written in restructure util we
should get the value as the same type
as that of datatype of columnschema in restructure util earlier in master
branch in restuctureutil class if our data type is long or short or int we are
always returning back a long object which is wong due to same reason compaction
was failing
if it was applied after alter table add columns command with default value
because in sortdatarows there was mismatch between data type and its
corresponding value
**Testing:**
1.mvn clean install is passing
2.added new test case for same
